So you claim/reserve a private good, with no intention to use it. Just so others can't use it?

That said, should there be some sort of central internet registry where we all registered our unique usernames which will be the same and reserved on every platform?

This reminds me of the days of EFNet where you would fight to have a username. If you stopped using it/disconnected, it was fair game.

I don't think someone would start posting malicious messages to make you look bad. They would just use it for themselves, with their own profile pic and would be obvious it's not you.
